A New Method of Building Grey Forecasting Model

摘要：

Based on the modeling mechanism, the background value of accumulating method GM(1,1) model is reestablished, and its forecasting formula changed from white respond to connotation type. The theoretical analysis indicates that the improved modeling method extends the significative region of the model. And, results of the followed simulated test and the applied examples show that the new modeling method is suitable for either low-growth series or high-growth series, and has a very high precision for both short-term and long-term prediction. It extends the applicable range of GM(1,1).
